The invention relates to covers for the openings in metal receptacles,such as her role, cans, tank cam etc; and the invention consists-inproviding a simple metallic closure which does not require packing toseal joints suli'iciently for carrying oils and simiiarliquids whichrequires sealed joint; and thein'vention consists in lhe constructionand arrangement of the parts" as described in this specification andshown in the accompanying drawings and pointed out in the claims.

Fig. 3 is gfi iview of the rim for holding the cover. l is planview of the under side of the cover. Fig. 5 is a sectional View of thebarrel at line Y Y in Fig. '1. r

Like numerals of reference refer to corresponding parts in the severalviews.

The numeral indicates the receptacle; the numeral 11 the rim on thereceptacle for holding the cover 12. The receptacle 10 may extenclvertically from the rim 1 that is, the cover 12 and rim 11 may cover ise entire end of the receptacle 10, or the cover Y12 and rihi ll mayextend over only a portion of the endof the receptacle and is preferablyset into the same, as shown in dotted line 13 in Figa'l.

The rim 11 is arranlgfd with an inwardly extending flange 14 w ich haspreferahl a tongue 15 extendin around the same.

therein just below the flange 14 and at spaced distances to receive thethreaded nuts 17 for the attaching bolts 18. The holes or openings 16are made to slidably fit the nuts 1? so fithat they cannot thrn therein;The flange 14: has correspondingly spaced holes 19 extendingther'cthrough into the openings 16 said holes 19 are outside of thetongue 15. v

rim 11 has also t e holes or openings 16 The cover 12 is provided withspaced holes 20 corresponding to the holes-19 to receive the screw bolts18 for attaching the coral;v

12 to therim 10. A groove 21 isprovided; I

around the under side of the cover lh to lit the tongue 15. Both thetongue 15 and the groove 21 are ground so as to fit oneyanother and forma liquid tight joint between the cover and rim. The bolts 18eXt/endthrough the cover and flange 14 over openings 16 and are turnedinto the threaded nuts 1?, drawing the cover down firmly upon. thetongue 15. 'llhis arrangement makes it po e sihle tos use common screwholts and" at the same time the bolts 18 obtain a strong lov'rage on thecover 12 inholding it upou' the tongue 15. v M c v The tongue 15 andgroove 21 are sofitted to one another that tongue 15 does not reach,

to the bottom ofgroove 2l and the gradual opening of the preferablyif-shaped ground sides of the groove 23. form such close coritact withthe correspondingly inclined" ground surfaces of tongue 15 that n fluidtight goint or liquid seal 18 formed between these suriaces. Asufficient number of halts l8 areuscd to firmly attach th'ecover '12 tothe run 11. Fornunqerous reasons; how-' ever, the present arrangement ispreferred.

The openings lo are preferably made in projections just beneath theflange 1% so that said openings 16 are entirely closed from the interiorof the receptacle. After the nuts 17 are inserted the mouths of theopenings -16 are preferably closed either with wooden plugs 23 or was:or soihmetal.

ln-order to remove the cover 12 it is often necessary to start saidcover frcm the tongue 15 since the parts fitso tightly to gather as toadhere strongly. Accordingly handles 22 are provided on cover 12 whichhandles are so placed that a lever ma he thrust under a handle 22 andwill near across the-top of the rim 11 thereby chi-aining a strongleverage which will so si! 5 start the cover and permit its removal. I

Should the joint between the rim and cover, formed by the tongue 15 andthe groove 21, become impaired in any way so that the liquid seepsthrougglti said joint;

it may he quickly and cheaply repairedhy' dropping 011 and. emery intothe groove 21,
